Process tomography of quantum memory in a Josephson-phase qubit coupled to a two-level state
Defects in Josephson junctions are considered a nuisance when it comes to using superconducting circuits as building blocks for a quantum-information processor. But if the interaction between the circuit and defects is accurately controlled?as has been demonstrated now?the imperfections might be useful, serving as memory elements.
